Simplify the quotients in Exercises 21–28 without using a calculator.
$\frac{8!}{10!}$

Short Answer

Expert verified

The value is $\frac{1}{90} .$

Step by step solution

Step 1. Given information.

The given expression is $\frac{8!}{10!}$ .

Step 2. Value of the expression.

Now,

$n! = n (n - 1)! \frac{8!}{10!} = \frac{8!}{10 \times 9 \times 8!} = \frac{1}{90}$

Explain why a function a(x) has to be continuous in order for us to use the integral test to analyze a series $\sum_{k = 1}^{\infty} a_{k}$ for convergence.

Find an example of a continuous function f : $[1, \infty) \to R$ such that $\int_{1}^{\infty} f (x) d x$ diverges and localid="1649077247585" $\sum_{k = 1}^{\infty} f (k)$ converges.

Determine whether the series $\sum_{k = 0}^{\infty} \frac{3}{2^{k}}$ converges or diverges. Give the sum of the convergent series.

Use the divergence test to analyze the given series. Each answer should either be the series diverges or the divergence test fails, along with the reason for your answer.

$\sum_{k = 1}^{\infty} \frac{k}{3 k + 100}$

Given that $a_{0} = - 3, a_{1} = 5, a_{2} = - 4, a_{3} = 2$ and ${\sum a_{k}}_{k = 2}^{\infty} = 7$ , find the value ofrole="math" localid="1648828282417" ${\sum a_{k}}_{k = 1}^{\infty}$ .
